Calcium molybdate nanostructures have been successfully prepared via coprecipitation approach byutilizing Ca(Sal)2 (Sal = salicylidene) and ammonium heptamolybdate ((NH4)6Mo7O24 4H2O) as startingmaterials in water as solvent. The products were characterized by Fourier transform infrared (FT-IR)spectra, X-ray diffraction (XRD), energy dispersive X-ray microanalysis (EDX), photoluminescence (PL)spectroscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Theeffects of temperature, reaction time, solvent, surfactant, calcium source and pH were considered toobtain optimum condition. It was established that morphology, particle size and phase of the finalproducts could be extremely affected via these parameters. It revealed that utilizing of water as solventand NH3 as the base, provided octahedral and hierarchical self-assemblies nanostructures, respectively.
